Popped the cap, yup it’s a 6 speed.
The crud was so etched in the cases, I used a descaler air tool to chisel it clean. Baked on oily grass crap. Got it clean tho, then scrubbed gasoline and paint thinner. Good enuff, The dirty part is contained so I don’t have to wash my hands 80 times ya know,
The original pulley is 8” like a moby pulley, ditched that for a 5” pulley.
Only problem is it don’t fit without moving the axle mounts,,, again! :) then I’ll have to move the motor back so the pulleys don’t collide.
